The invention relates to a process and longitudinal sieve paper-machine for manufacturing multiple-course pa ers, cardboards and the like, provided wit several upper,

5 independent sieve-aggregates. Such a machine forms for instance the subject matter of American patent-application Ser. No. 4,250, filed Januar 23,1925, now Patent 1,727,162, granted eptember 3, 1929. The

lower longitudinal. sieve is therein however made as shaking sieve-element and the compensating shaking of this longitudinal sieve is only eifected after the last, upper shaking machinery aggregate. The nature of the present invention on the other hand consists therein, that the lower longitudinal sieve is non-shaking, i. e. stationary, while the upper, indepen ent working paper-machineryaggregates possess normal shaking. Com- J pensating shaking is hereby effected between the single independent working machineryaggregates and the lower, non-shaking longitudinal'sieve. This compensating shaking can for instance be effected in an extension of i the upper sieve, or a specially installed intermediate element between the shaking, upper sieve and a nonshaking lower longitudinal sieve.

The construction of the machine according to the present invention renders it possible, to manufacture multiple-course papers, cardboards or the like with a flaky covering layer, whereby the-lower, non-shaking, lone gitudinal sieve must contain the coveringlayer, upon which the paper-layers of the upper sieves are placed consecutively. A multiple course product is hereby obtained, the lowermost layer of which (covering-layer) has been produced by non-shaking, while the other layers are made with any'desired shaking. The layer of material upon the lower, longitudinal sieve, can of course be omitted. In this case, only the layers of the upper sieves would be placed upon one another and a multiple course product would be obtained, the layers of which have been made by any desired shaking.

Five different embodiments of the invention are illustrated in the accompanying drawings and,

13-15 show the other embodiments of the invention by corresponding illustrations. 1

Like reference-marks indicate like parts in all figures.

Reference numeral 1 is the lower, longitudlnal sleve, made non-shaking, i. e. stationary and at the under side of its upper course is -I)IOV1d6d with suction-boxes. 10 is the front roller, 11 the sieve-table vof the lower longitudmal sleveor so-called .Fourdri'nicr wire 1, provided with register-rollers 13 and registar-rails 15, and guided with its lower course PAPERS, cmmsoaanam rnn around the sieve-guiding tension-rollers 14,

while theregister-rails are firmly connected with rigid, non-shakin support or frames 17 which are attached rmly to the floor, so

that the lower, longitudinal sieve cannot shake.

The circular sieve-rolls 5 ofthe upper, in-

and 3' are, b thepivots 16 supported in the frames 17 stead of two upper aggregates, more than two might be of course arranged -consecutivel 6 indicates the frontroller, 7 the sieve an .8 the suction-boxes one for each upper aggregate each. The register-rails 18 with the support of the segment-like shakingpart (compensatin -shaking) arelinked to the supports'17. I or supporting the shaking-device, a frame or bracket B has been provided. This device comprises a continuous shaft 20, upon which a cone-pulley 24 is mounted, driven by a belt 25 from another cone-pulley 23, supported by the bracket B, which pulley 1s driven'by any suitable means (not illustrated). The shaft 20 car- 'ries further an eccentrlc 21, acting updn the shaking-bars 22, engaging the register-rails 15:"and bearing18 of the'upper machineryaggregates, as shown in Figs. 2 and 3.

In Figs. 4, 5 and .6, the upper shaking sieves 2 and3 are suspended on a frame A, as far as they are shaking parallel. -'The two upp machinery-aggregates 2 and 3 are further -aggregates 2 connected by a frame C and this frame is engaged by the shaking-bars 22 (instead of by the register-rails of the upper sieves as shown in Figs. 1, 2 and 3) Each upper sieve (2 or.3) can practically be arranged so that it will be possible to work with several shaking-brackets B, see Figs. 1 and 3 and thereby impart to each upper sieve a special shaking. The upper sieves 2, 3 are extended downwardly over the cylinders 5 for enabling the compensating shakingand each passed over one roller on the support 17 (Fig. 4).

The frame A is required, if the compensating shaking is efiected, as shown in Figs. 4, 5 and 6, in an extension of the upper sieve or, as shown in Figs. 7, 8 and 9, in a separate, independently working, intermediate element. The latter replaces therefore the extension of the upper sieve and is installed between the lower non-shaking longitudinal sieve 1 and the cylinder 5 of the upper shaking-sieves 2 and'3. It consists of two upper press-rollers 26 and 27, one lower roller 28 and one sieve 29. Each roller 26 contacts with the respective sieve-cylinder 5 of the upper sieve 2, or 3, in order to guide the papercourse of the respective upper sieve, while the lower roller 28 places the material, coming from the respective upper sieves, upon the longitudinal sieve 1.

The shaking-bars 22 engage as before with the frame C, and the roller 27 joinsthe sieve 29 in the shaking of the respective upper sieve, as this roller 27 is supported with the entire upper sieve in the frame C, while the roller 28 is stationary and non-shaking, being attached to the register-rails 15 of the lower non-shaking longitudinal sieve. From the stand-point of compensating-shaking the machine according to Figs. 10, 11 and 12 difiers from the machine according to Figs. 4, 5 and 6, iust the same as the machine according to Figs. 13, 14 and 15 differs from the one according to Figs. 7, 8 and 9 namely thereby,-- that the register-rails 18 of the upper sieves instead of the frame 0 are provided and engaged by the shaking-bars 22. The

sieve-cylinders 5 of the upper sieves 2 and 3 are furthermore supported with the axles 16 intermediate elements (Figs. 13-15) by the correspondingly raised supports 17 of the.

lower longitudinal sieve 1." In this case, the frame A is of course superfluous for supportmg the upper sieves.

I claim:

1. In a multiple wire paper-machine, the

(Figs. 10-12) and the rollers 26, 27 ofthe 1 mounted in each of said frames and in said' support and a connecting belt between the respective rollers.

In testimony whereof I afiix my signature.
